Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-19311 in the wild and no public exploit code.\n\nAffected product: AWS OpenSearch. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-19311/ (Markdown: https://insights.sbomify.com/CVE-2026-19311/index.md)","id":"CVE-2026-19311","markdown":"https://insights.sbomify.com/CVE-2026-19311/index.md","name":"CVE-2026-19311","record":{"aliases":["GHSA-4v32-vrp2-28jp","GHSA-xxpg-q3wh-685q"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSearch Alerting Plugin","requires_auth":"low_privilege","summary":"Authenticated users can read, modify, or delete arbitrary index data via the Execute Monitor API due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"AMZN","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-475","name":"Undefined Behavior for Input to API"}],"description":"Missing authorization in the Execute Monitor API in Amazon OpenSearch Alerting plugin might allow an authenticated remote user to read, modify, or delete arbitrary index data via a crafted inline monitor request with unintentional data source and input index parameters.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Missing Authorization in Execute Monitor API in OpenSearch Alerting Plugin","id":"CVE-2026-19311","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Fireware OS Pre-Authentication Heap Buffer Overflow in iked Allows Remote Code Execution","id":"CVE-2026-19313"},"packages":[],"prev":{"headline":"Path traversal in Langflow OSS","id":"CVE-2026-19306"},"products":["OpenSearch"],"published":"2026-08-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-08-13","vendors":["AWS","Github"]},"summary":"Authenticated users can read, modify, or delete arbitrary index data via the Execute Monitor API due to missing authorization checks.","url":"https://insights.sbomify.com/CVE-2026-19311/"}
